The objects of the invention are to provide a simple and eiiicient formof a driven and self puncturing and pouring tube or faucet for a sheetmetal container, and which is so constructed that the faucet tube whendriven will cut its own way through the side or top of the can, and willprovide an opening through which the liquid'will enter the faucet.

The invention also provides means for leaving an unsevered neck orconnecting part between the cut out portion and the wall of the canwhich willprevent that portion from falling into the can. 1

l The invention also provides means foranchoring the faucet tubesecurely in the opening which it has made, and means for sealing theopening so that the container will remain air tight after it'has beenpunctured.

The faucet-tube is preferably constructed from a sheet metal blank orstamping; and locking bosses, and screw threads for the adjustment of, aclamping or wing nut and terminal eyes for'the attachment of a pivotedvalve or closure, may be simultaneously formed upon the metal blank. 7

To accomplish theseand other useful results the invention comprises, themethod of construction and the combination and ar-.

F0 rangement of parts, hereinafter described, il-

lustrated in the accompanying drawings and particularly pointed out inthe claims.

In these views A isthe tube, which is first.

stamped from a sheet of metal in the flat form shown in Fig. 5 and isthen shaped into a tube as shown in Fig. 3 with the longitudinal edgesclosely meeting atB. These edges may then be cemented or soldered tight.YVedge' shaped pointed cutting projections C, 0, dia- 50. metricallyopposed toeach other are formed.

- At the upper edge of the blank are the ears M, M, upon which hingeears N, N, p of the finger operated valve, Q, are pivotedflgo P is thepivot pin therefor. and Qis a compression spring which retains the valvein position'when released from the finger.

A washer B may be set .in a recess S in V the upper end of the tube asshown in Fig. 1a, or a rubber disc R. may be set in the valve 0 as shownin Fig. '1. v

The device is easily placed,first, bydriving the tube through the wallof the container and then by revolving the same'until the bosses I 3.10"

engage underneath the wall of the container. The wing nut is thenrevolved until the tube is firmly secured in place.

Having described the invention what we claim as new and desire to secureby Letters Patent is 1. A blank for a sheet metal driving tube, saidblank having spaced points at its lower edge separated by deep recesses,one. recess being cut deeper than the other and provided with bossesimpressed therein and spaced therefrom, and also provided with a trans.-verse portion composed of screw threads impressed thereon.

2. In a driven faucet, a tubular body, having' diametrically oppositeangular extremities forming piercing points, the sides of said pointsbeing bevelled to form cutting edges,

and adapted to turn down the opposite edges of the opening producedthereby, said tubular body being provided with diametrically opposedbosses which when said body is revol ved will engage underneath saidturned down edges and means adjustable-on said bodyfor clampingsaidbosses upon said turned down edges, the recess upon one side of saidtube between said piercing points being' deeper than the recess upon theother side to provide an unsevered neck to prevent the total detachmentof the piece partially severed from the wall of the can.

3. A driven faucet tube comprising, a rolled sheet metal stamping havingits longitudinal meeting edges welded together, and having screw threadsraised thereupon intermediate of its ends, a clamping nut therefor, theinner end of said tube being bevelled to provide opposite cuttingpointswith sharp edges, the recess in one side of said tube being deeperthan the other to prevent the complete release of the portion cut awaythereby, and opposite bosses on the sides of said tube intermediate ofsaid bevelled and threaded portions and a clamping nut on said threadedportion.

In testimony whereof we aflix our signatures.
